JOHN A. BRILL AND GEORGE MARTIN BRILL, OF PHILADELPHIA, PENNSYLVANIA.

RAILWAY-CAR TRUCK.

SPECIFICATION forming part of Letters Patent No. 433,932 dated August12, 1890.

Application filed October 2, 1888- Serial No. 286,958- (No model.)

To 00% whom it may concern:

Be it known that we, JOHN A. BRILL and GEORGE MARTIN BRILL, citizens ofthe United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Railway-Oar Trucks, of which the following is aspecification.

Our invention has relation to independent rigid trucks for street-cars,or that form of trucks which, while rigidly secured to the car-body incontradistinction to pivoting the truck to the car-body, is removabletherefrom, such as shown in Patent No. 425,653, granted to us April 15,1890; and it has for its object a construction of independent truckframewherein an electric or other motor may be mounted wholly upon thetruck-frame, or partly thereon and partly upon the car-axles, wherein alight-weight and separate axle-box frame is provided for supporting thefenders, track-brushes, track brake-shoes, and sandboxes, and wherein apost form of pedestals may be used for the aXle-boxes, said truckframebeing rigid and strong enough for all conditions of service and readilyattachable to and detachable from the car-body.

Our invention accordingly consists of the combinations, constructions,and arrangements of parts, as hereinafter described in thespecification, and pointed out in the claims, reference being had to theaccompanying drawings, wherein Figure 1 is an elevation of anindependent box-frame supports detached from the truck.

Fig. 5 is a detail elevation, partly in crosssection, of the truck-frameupper and lower chords and connections; and Fig. 6 is a sectionalelevation showing another form of axlebox-frame support.

A represents the independent rigid or other truck-frame, composed of atop frame B,having side bars or chords b b, and end cross-bars b, and,if desired, intermediate cross-bars 19 which are suitably securedtogether and may be of any suitable material and of any suitableconfiguration in cross-section, as desired; but we prefer to make it offiat bar-iron, the parts of which are forged together to provide a frameB in one piece when completed.

To frameB are secured the axle-box pedestals or supports G, which may beof any suitable kind or make; but we prefer that form of same known asthe post form, and which is shown as consisting of grooved top plates 0,embracing the side bars or chords 1) of frame B, and having smoothopenings near their ends for the passage of the upper ends of the posts0, which post ends may be threaded and shouldered and screw into thesides I) offrame B, as indicated, and as fully shown, described, andclaimed in another pending application filed by us of even dateherewith, Serial No. 286,957. If desired, however, the posts 0 may besecured to the frame sides I) in any other suitable way.

The axle-boxes D are provided with springseats d, through which theposts 0' pass, and the latter are, if desired, provided with the mainsprings E and secondary top and bottom springs e and 6', respectively,and suitable caps or plates are interposed between said springs, asfully set forth in said other pending application, or any other suitablearrangement of springs between the axle-boxes and truck-frame may besubstituted for that shown.

F F represent lower side bars or chords for the truck-frame, whichchords may be connected to the axle-box pedestals, or the posts 0 of thelatter may pass through and slide in openings in the chords F, asindicated. The end sections f of the chords F are preferably separatefrom the main secti'onsf, and are bolted thereto and to the frame B, sothat the main sections f may be removable from the truck to admit ofinserting the axle-boxes in position when building the truck and fordismounting the same for purposes of repairs or replacement. The main-.chord-sections f may be of any suitable form in cross-section; but weprefer to use the ordinary commercial angle-iron therefor and connectthem by suitable corresponding or other cross-bars f which cross-barsare preferably arranged or located near the transverse center of thetruck-frame or between the wheels to afford a rigid and strongfoundation for wholly supporting an electric or other motor thereon, orfor partly supportingit thereon and partly on the axles, as indicated atG, Fig. 1. If desired,'the cross-barsf may be connected to frame B andthe motor secured thereto, as above described.

The lower chords F and the sides or chords b of frameB are near theirtransverse centers connected by V or other shaped brace-rods 1 andvertical pillars or posts2' 2', to prevent the truck-frame sagging orbending at its transverse middle, and for economy of construction Weprefer to secure the brace-rods I and posts 2 to said chords and thecross-bars f to the lower chords F, as more plainly shown in Fig. 5,wherein are indicated clips h, having bent ends h secured to the lowerside of the horizontal wingor top of the crossbars f which bent ends hare bolted, as indicated at 77. to the vertical sides of thechordsections f, and other corresponding clips 72 are bolted to theupper side of the top of the cross-bars f Said clips 72, and thehorizontal or upper sides of the chord-sections fand the brace-rods Ihave openings through which' the posts 2' pass, and all of said partsare firmly bolted together and to the posts by means of collars 2" andnuts 2' on the lower ends of the posts 2'. The upper ends of the posts 2are connected or secured to the frame chords or sides I), as shown, orotherwise, as desired. The ends 2' 2' of the brace-rods I may be securedto the frame sides or chords 1) or to the opposing ends of the pedestalcastings or plates 0, as desired.

The brace-rods I may be in one piece or be composed of separate rods, asindicated in Fig. l of the drawings.

When the truck A is used on summer-cars, or those having an extremelength, brace or truss-rods K, between or joining the ends of the carand the chords or pedestal connecting bars F, are preferably employed,and the junction or coupling for the chords F and the brace-rods K maybe of a construction as shown in our other aforesaid application, or asshown in the drawings, wherein either the chord-sections f or f" areformed with an angularly-arranged pin or foot f for engagement with orinsertion into the bore of the end of the tubular brace-rod K, as shownmore plainly in Fig. 2, the opposite end of said brace-rod sliding intubular brackets 70, secured to the ends of the car and being eX-teriorly threaded and provided with j ain-n uts k (see Fig. 2,) so thatsaid pin-couplingf between the braces K and chords F, may be made anddisconnected by simply adjusting the jam-nuts 70 k? and sliding thebrace-rod longitudinally to admit of easy removal of the truck from thecar-body and of attachment thereto.

M represents the axle-box frame, which may be constructed of wood orpartly of wood and iron, as desired, to make it of light weight, as itdoes not support the motor, and it has end fenders 222. Frame M may besecured rigidly to the axle-boxes or to depending or other located lugsd thereon, as indicated in Fig. 6, or it may have any suitable form ofspringlink or other support upon or connections with the axle-boxes. InFigs. 3 and t we have shown modified forms of said springsupports,wherein (1 represent vertically-arranged tubular lugs secured to orforming part of the axle-boxes. These lugs may be located between thesprings E and the axleboXes forming an integral part of the springseatsd, as indicated in Fig. 3, or located on the sides of the boxes neartheir outer ends, as illustrated in Fig. 4, or otherwise, as desired.Through these lugs (2 pass bolts (1 connected by flat metal bars d towhich the frame M is secured in any suitable manner. The springs d forthe bolts 61 may be arranged or located between the head of the bolts 61and the top of lugs (P, as indicated to the left of Fig. 3, or belocated within the bore of said lugs, as shown to the right of saidfigure.

The axle-box frame M, it will be observed, is independent of thetruck-frame supporting the motor, and upon frame M may belocated thetrack-brushes, track brake-shoes, and sand-boxes, as fully set forth inour aforesaid other pending application, or, if desired, the sand-boxesmay be secured to frame B or chords F.

If desired, the main section f of the lower chords F of the truck-framemay be made sectional, as indicated at f, Fig. 3, so that the ends ofsaid sections bridging the axle-box pedestals may be removed Whenever itis desired to dismount the axle-boXes withoutnecessitating removal ofthe brace rods I and posts 2. So, too, if desired, elastic buffers orsprings c may be placed on the posts 0', be-

tween the aXle-boxspring-seats d and the lower chords F, to compensatefor or take up the jolting vibrations of the wheels on the rails.

As the novel features of our improvements may be greatly varied withinthe spirit of the invention, we do not confine ourselves to the same asshown and described.

hat we claim is- 1. The combination of the upper longitudinal chordsadapted to be rigidly secured to the car-body, and having pedestalssquared thereon, the lower longitudinal chords extending approximatelyfrom end to end of and connected to the upper chords, truss or bracerods and bolts connecting said upper and lower chords intermediate ofthe pedestals to form a truss, and cross-bars connecting said trusses,for the purpgse set forth.

2. The combination of a rectangular frame, the sides of which form theupper chords of trusses on the sides of a truck, and having thepedestals secured and squared thereon, the lower longitudinal chordsconnected together by cross-bars and extending from end to end of theupper chords, to Which they are secured, and truss or brace rods andbolts connecting said upper and lower chords intermediate of thepedestals, for the purpose set forth.
